What Are the Causes of Rosacea?

Overview

Rosacea is a skin disorder that is characterized by redness, inflammation and small bumps that appear like acne on the face. The condition is chronic, and affects adults. No cures exist for rosacea, but treatments like topical creams and diet modifications can help manage the signs and symptoms. According to the Mayo Clinic, the causes of rosacea are unknown, though certain factors can make you more susceptible to the disorder.

Fair Skinned

Rosacea tends to affect fair skinned individuals and can be prominent due to the redness that results from enlarged blood vessels under the skin, or increased vascularity (spider-like blood vessels). The condition is chronic and tends to flare up for periods lasting from weeks to months, according to the Mayo Clinic.

Blush Easily

Rosacea may also be more likely to occur among those who blush easily, and can cause a burning or stinging sensation on the face. Those who suffer from rosacea may also have a red, bulbous nose, due to inflammation that can occur. To control these symptoms, an over-the-counter or prescription such as oral antibiotics or topical creams may be used. Applying sunscreen and protecting your face in the winter can also help reduce irritation.

Age

Age can also be a factor for those with rosacea. The condition usually affects those who are between 30 and 50 years old. Eruptions that ooze or crust over can also be seen on the skin, and may appear like acne. Often the condition is mistaken for acne, and acne treatments like tetracycline, minocycline or doxycycline can be effective in treating the condition, according to Medline Plus. Accutane (isoretinol) is another prescription that is used to treat severe forms of acne and can aid those with rosacea.

Gender

Gender is another factor that can influence the likelihood of developing rosacea. Women are more likely to be diagnosed with the condition, though the condition is often more severe among men. Certain practices can help reduce the irritation, like using make-up that is noncomedogenic (will not clog pores) and gentle cleansers like Dove and Cetaphil. Avoiding products containing alcohol and harsh ingredients is also recommended by the Mayo Clinic, as is moisturizing after medication is applied. To disguise the appearance of rosacea, women can also wear makeup with a green or yellow tint and practice yoga to relieve stress, which can aggravate the condition.

Considerations

According to the American Academy of dermatology (AAD), rosacea can also affect other areas of the body and affects the eyes in approximately 50 percent of the people who have rosacea (resulting in itchy or watery eyes). Additionally, while rosacea is most common on the face, a recent study indicated that some people who have rosacea do not have it on their face at all but rather on their back or elsewhere.
